FIG. 1.

PCFs of the quasi 2D Cu during cooling with four different cooling rates (i.e., 500, 250, 100, and 10 K/ps). The brown curve represents the PCF without the splitting of the second peak, the blue represents that with the splitting of the second peak, and the green is the typical crystal peak.

FIG. 2.

(Left) Local atomic arrangement of the quasi 2D Cu at 300 K with the cooling rate of Q2 = 250 K/ps. Blue: atoms with crystal-like ordering; others: fully disordered ordering. (Right) From top to bottom: PCF curves of the local crystal-like region, fully disordered region and global region.

FIG. 3.

PCF curves of the liquid, amorphous, and ideal crystal Cu; red line: liquid Cu at 1800 K; blue line: solid Cu at 300 K (cooling rate: Q = 400 K/ps); green line: solid Cu at 300 K (cooling rate: Q = 200 K/ps); black line: ideal crystal Cu. R1, R2, R3, and R4 represent the ideal fcc peaks, respectively.

FIG. 4.

Relationship between the fraction of the crystal-like region and the splitting of the second peak with different cooling rates: black line: 500 K/ps; red line: 250 K/ps; blue line: 100 K/ps; brown line: 50 K/ps; purple line: 25 K/ps; and dark blue line: 10 K/ps.
